April 2025: Key feature delivered in DEFRA/epr-common-data-api: IsNewJoiner-based late fee calculation for Registration Fees. Updated data models, service logic, and stored procedures to capture and process IsNewJoiner status for accurate late fee assessment. This enables compliant, accurate billing for new joiners and reduces manual intervention. Commit 32d0fe03731cfb80b8d47522621a990f4028c952 (546757-CSO-Late-Fee-reimplement (#196)).

February 2025 monthly summary for DEFRA/epr-common-data-api focused on delivering a scalable, streamlined API surface for registration fee calculations and improving data retrieval paths. The work prioritised business value through reliable fee lookups, reduced maintenance overhead, and a cleaner API structure that supports downstream systems with greater consistency.

December 2024 highlights two cross-repo improvements that strengthen reliability, maintainability, and business value. In DEFRA/epr-common-data-api, a Database Parameter Handling Refactor and No-Key Query Models was implemented by instantiating SqlParameter directly and configuring no-key query models in SynapseContext, reducing parameter handling errors and simplifying query results. In DEFRA/epr-facade-account-microservice, payment processing was migrated to a dedicated packaging frontend service, decoupling payments from core account creation and enabling independent evolution and deployment. These changes improve system stability, reduce coupling, and support faster feature delivery.

November 2024 monthly summary: Delivered key API features and reliability improvements across two DEFRA services, with a focus on data accuracy, secure access, and payment flow stability. The work enabled better data retrieval by organizations, expanded CSO member visibility, and a smoother, more reliable payment initiation process, contributing to improved user experience and operational risk reduction.
